Update 0.22

* Game has four game speeds. Paused, Normal Speed, Fast Speed, and Fastest!
* Game saves will also remember the game speed.
* Removing buildings that give happiness, now will remove happiness too!
* Fixed "Add All Workers" or "Add All Robots" in the work window, won't give nagitive villagers or nagitive robots.
* Able to destroy resources. Eg: trees, mushrooms, heal plants,etc.

Will be going through balance changes in the buildings so its easier to expand.
